standard, and arranged in fixed relation T 0 all whom it may concern:

Be it known that l, BRINTON M. NATION, a citizen of the United. States, residing at Bloomfield, in the county of Greene and State of Indiana, have invented a new and useful Bolt Tightener and Cutter for l/Vheels, of which the following is a specification.

This invention relates to improvements in tools for applying and removing the bolts employed for securing tires on vehicle wheels, and it has for its object to provide an improved device of this character that is capable of parts, which will be hereinafter more fully described, and pointed out particularly in the claims appended hereto.

1n the accompanying drawings Figure 1 is a central vertical section of a tool of the character described constructed in accordance with the present invention. Fig. 2 is a bottom plan view of the device shown in Fig.

1, the cutter being removed. Fig. 3 is a front elevation of the operating mechanism. Fig. 1 is a detail view of the cutter and its operating lever. Fig. 5 is a diagrammatic view showing the mode of removing the bolts from a vehicle wheel. Fig. 6 represents an axial section of the nut wrench. Fig. 7 is a bottom plan view of a nut wrench. Fig. 8 represents a top plan view of the wrench actuating gear. Fig. 9 represents an axial section of the wheel shown in Fig. 8. Figs. 1.0 and 11 show the extracting lever in bottom plan and side elevation, respectively Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The device shown in the present embodi ment of the invention comprises a hollow standard 1 suitably secured to a post or other support, bolts 2 and 3 carried by a bracket 4 cooperating with the standard in the present instance to secure it in position, the bracket in turn being secured to the post 5 by means of bolts 6 and 7. At the lower end of the thereto, is a bed 8 having a vertical bore 9, adapted to form a bearing for a nut wrench 10, the latter, in the present instance, being substantially cylindrical and having an angular socket 11 at its upper end to receive the nuts which serve to retain the tire securing bolts in place, and below the socket the wrench is bored out, as at 12, to form a pas sage for the nuts after they have been removed from the bolt.

Below the nut wrench and arranged with its axis in alinement therewith is an actuating gear 13 having an upper journal portion 14 extending into the bearing 9 0f the bed and having a clutch face formed in the present instance by projections 15 which cooperate with correspondingly formed recesses 16 in the lower end of the wrench, the clutch thus provided serving as a guiding connection between the actuating gear and the wrench and permitting wrenches of difierent sizes to be interchangeably fitted. The lower journal portion 17 of the gear extends through an aperture forming a bearing in the plate 18, the latter cooperating with the lower side of the gear to support it. This supporting plate is secured to the under side of the bed by means of a pair of bolts 19 and 20, the bolt 20 serving as a journal for an intermediate gear or idler 21, which cooperates with the wrench actuating gear and with a gear 22 fixed to the lower end of the driving shaft 23, the latter being journaled in the standard andcarrying a bevel gear 24 at its upper end.

Any suitable means may be employed for operating the driving shaft, it being preferable to employ operating mechanism that is capable of being reversed in order that the wrench may be turned in two directions, that is to say, in a direction to tighten the nuts, and in an opposite direction to loosen or remove the nuts. The operating means shown in the present instance embodies an operating shaft 25 j ournaled in the arms26and 27 of a yoke 28 fixed to the upper end of the standard, a pair of oppositely arranged bevel gears 29 and 80 being fixed to the operating shaft between the arms of the yoke, and the operating shaft being capable of a limited axial movement for shifting the gears 29 and 30 alternately into cooperating relation with the gear 24 on the vertical driving shaft. In order to retain either of the gears on the operating shaft in cooperative relation with the gear on the driving shaft, it is preferable to employ a suitable retaining device which comprises, in the present instance, a yokeshaped member 31 which is adapted to fit over and rest upon the shaft between the gear that is in mesh with the gear 24 and the adjacent arm of the yoke. The operating shaft may be turned in any suitable way, a crank 32 being shown in the present instance for operating it.

It is advantageous to employ a bolt cutting attachment in connection with a machine of this character whereby those portions of the bolt projecting beyond the nuts, after the latter have been tightened, may be removed, and the bolt cutter shown in the present instance embodies a lever 33 mount- 3 ed between the arms 34 and 35 at the outer end of the bed and pivoted to turn on a pin 36, the upper end of the lever being provided with a cutting edge 38 arranged adjacent to the plane of the top of the bed and it cooperat es with a shoulder 37 to effect the severing of the bolt end. The lower end of the lever enga es between the arms 39 and 40 of a turn buc rle, a bolt 41 serving as a pivotal connection between the cutter and the turn buckle, the opposite end of the latter being threaded to receive the longitudinally adj ustable bolt or screw 42 which is pivotally connected at 43 to an operating lever 44, the latter being fulcrumed at 45 and secured to a relatively fixed support by the bracket 46.

In order to facilitate the extraction of the bolts from the wheels and to prevent their turning while being tightened or loosened, I provide a lever 47 having one end mounted between the forwardly projecting bearing arms 48, the pin 49 serving as a pivotal con nection, and this lever is provided with a pointed tool or chisel 50 which is secured therein by a set screw 51, orother suitable means, the operating face of this chisel being so located relatively to the pivot of the lever that it will be arranged in alinement with the axis of the wrench when the lever is turned into operative position, the chisel bearing upon and obtaining a hold on the head of the bolt extending through the wheel tire and serving to prevent its rotation during the tightening or loosening of the nut.

The lever is also provided with an opening 52 arranged at a point between the chisel and the pivot of the lever, and extending from this opening toward'the pivot are a pair of relatively fixed convergent jaws 53 adapted to receive the head of the bolt. In the moving of the bolts from the wheel, the nuts are first removed by means of the wrench, and then the wheel is moved toward the standard so that the head of the bolt is in alinement with the opening 52 of the extracting lever, the threaded end of the bolt resting on top of the bed 8, and as pressure is applied to the wheel rim through the lever 47, the bolt will be forced outwardly through the rim, exposing the head thereof, and by moving the wheel again toward the standard, the head of the bolt will enter between the convergent walls of the lever and as the latter is turned upwardly, as shown in Fig. 5, the bolt will be drawn from the wheel rim, the bearing arms 48 cooperating with the rim to prevent its movement during the extracting operation.

In order to save the nuts after being removed from the bolts, it is preferable to employ a tray, that shown in the present instance being composed of sheet metal and having its arms 54 folded over the arms 39 and 40 of the turn buckle, the body of the tray resting between the arms of the turn buckle and forming a receptacle for receiving the nuts as they drop through the enlarged opening through the nut wrench and its actuating gear.

In applying and removing the nuts with a machine constructed in accordance with the present embodiment of my invention, the wheel rim is supported on the upper face of the bed 8, the nut to be removed being inserted in the angular opening 11 in the wrench, and while the wheel is in this position, the operating shaft 25 is rotated by means of the crank 32, the appropriate bevel gear thereon being 111 mesh with the gear 24 of the latter being communicated to the wrench through the cooperating clutch faces or projections, the bolt being held from rotation in cases where the nuts are rusted in place by means of the chisel 50, and the nuts may be tightened by a radial movement of the wrench in a reverse direction, the reverse movement of the wrench being obtained without the necessity of reversing the direction in which the crank is operated by shifting the operating shaft so that the appropriate gear thereon is in mesh with the gear 24 on the driving shaft.

The bolt cutter, as previously stated, is especially adapted for use in severing those portions of the bolts projecting beyond the nuts after the latter have been tightened, and the severing operation is performed by inserting the projecting portion of the bolt between the cutting edge 38 of the cutter and the shoulder 37, the operation of the lever 24 serving to proximate the cutting edge and shoulder.
